| Abstract: | Cerium is considered to be a
promising ecological alternative to toxic chromates in the field of corrosion
protection. Studies were conducted to evaluate the corrosion inhibition by
cerium on aluminium under marine and laboratory environments. The results
revealed that under marine environment 1000 ppm Ce treated pure aluminium
showed good corrosion inhibition than the Al-Mg alloy M57S. The corrosion rate
was significantly high during post monsoon and summer season and cerium treated
on pure aluminium showed superior corrosion inhibition in all the seasons.
Cerium treated pure aluminium showed better corrosion inhibition as compared to
untreated marine grade M57S aluminium. The laboratory evaluation of 1000 ppm
cerium treatment on aluminium and its exposure in solutions of different
salinity (5 to 200 ppt) revealed 30-66 and 0-92.6% efficient corrosion
inhibition in pure and M57S aluminium respectively. |
